I would love to help, but I can only trade on Gen V, which would be Pokemon Black/White.
If you can trade via B/W, I can help you out :D
If not, though, what you can do is post on the Quick Trade thread in the Trade Corner asking for donation Pokemon on Gen 4/SoulSilver. Someone there is bound to help you. Let me know if you need anything else, and I'll do the best I can
My name is Mick and I have a little nephew who loves pokemon. He got a nintendo 3ds and soul silver for christmas and since AR is not out where we live yet he needs some one to trade too. I'm not sure what you guys do normally for trades, but hes looking for anything that he cant get from a play through of soulsilver. Along with that some of the originals ( charmander, squirtle, bulbasaur). He doesn't have any of the rare pokemon yet I do not believe, but what would he need to trade you guys to get some of those pokemon? I ask you first because your post is massive and seem to know what your doing lol. My email is attached to this account, feel free to email me.
